Properties of Triangles

For these investigations we will be using the tangent ratio;

Tangent Ratio Formulas: Tangent Ratio = Opposite Side/Adjacent Side

Triangle Diagram

For these investigations we will be using the tangent ratio for triangles;

Tangent Angle = Opposite side / Adjacent side

Opposite side(object's size) = Adjacent side(distance) X Tangent Angle

Adjacent side(object's distance) = Opposite side(size) / Tangent Angle
